Email confirmation is a method for confirming user's email! Emails should be valid for future operations such as: mail notifications, newsletters, replying to posts from email, etc.

Phone verification make the process of confirming account stronger. It may also be a replacement for (re)Captcha.

Now, I was thinking about storing numbers such as Telegram, Viber and Whatsapp: It can be a method to have valid users! Some people make fake accounts for trolling. This can stop them a little! They should purchase more SIM cards to create more accounts

In some countries its actually really easy to get ahold of a SIM card. I'm from Malaysia and when I go there I can get a throwaway SIM card from any convenience store in about 10 minutes for a couple bucks

EDIT: Meanwhile in Canada.... :rage1:

They're free in the UK, but need an initial top up to activate, £1 would do this on some networks.

You can't install software on a domain.
A domain is just a name that gets resolved to a server (which you have to pay separately in most cases); This happens via DNS records.
So basically you need to buy a server (or host one by yourself which I don't recommend, especially for beginners) and a domain.
You set-up your domain to use the nameservers (NS) of your server provider (or the IP directly, but if your server provider has nameservers it's recommended to use them). In most cases you just tell your server provider which domain to resolve to which server and he'll generate a basic set of DNS records. After a period of 4 to 24 hours (in most cases) the connection between domain name and server will be established. In the mean time you can set-up anything on your server like NodeBB (you can test by using the static IP address of your server instead of domain name).
For a server provider a common choice is digitalocean which offers pricing from USD5 per month. You can get a USD10 credit using this referral link.
